Description

Technical Field

[0001] The present invention relates to the technical field of single crystal manufacturing, and particularly relates to a short single crystal picking and placing vehicle for a single crystal furnace. Background Art

[0002] At present, during the production process of single crystal rods, the breakage rate of single crystal rods is generally high, especially the breakage rate at the head of the single crystal rod is more prominent. At present, there is no effective solution for the breakage of single crystal rods, but the high breakage rate brings about the problem of picking and placing a large number of short crystal rods (with a length less than 1200 mm).

[0003] At present, the picking and placing of single crystal rods mainly rely on finished product crystal picking vehicles. However, the finished product crystal picking vehicles are mainly used for the picking and placing of long crystal rods and cannot effectively clamp and fix short crystal rods. Moreover, the process of picking and placing single crystal rods by the finished product crystal picking vehicles is relatively cumbersome and takes a long time. Therefore, at present, the picking and placing of short crystal rods mainly rely on the traditional transport vehicle plus manual handling. The picking and placing efficiency of short crystal rods is low. Especially for the horizontal placement of short crystal rods, at present, it can only rely on manual handling. The weight of the single crystal rod is large, and the temperature of the single crystal rod is high after being taken out of the single crystal furnace. Manual handling can only be carried out after the single crystal rod has cooled down, making it difficult to carry out immediate handling. Moreover, manual handling also has problems such as the risk of safety accidents and high labor intensity. Therefore, how to efficiently pick and place short crystal rods and place them horizontally is the problem to be solved in this application.

[0004] In view of this, this application is specifically proposed. Summary of the Invention

[0056] In the description of the present invention, it should also be noted that, unless otherwise clearly specified and limited, the terms "arranged", "provided with", "installed", "connected", and "coupled" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0057] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments:

[0058] As Figures 1 to 11 shown, this embodiment provides a short single-crystal picking and placing cart for a single-crystal furnace, which includes a cart main body 2 for transporting a short single-crystal rod 1, a rotary clamping module 4 for clamping and placing the short single-crystal rod 1, and a driving module 3 for driving the rotary clamping module 4 to move freely in the vertical direction. The rotary clamping module 4 is arranged on the driving module 3, and the driving module 3 is arranged on the cart main body 2;

[0059] The rotary clamping module 4 includes a fixing frame 41, a rotary assembly 42, and a jaw assembly 43, wherein:

[0060] The fixing frame 41 is arranged on the output end of the driving module 3. The rotary assembly 42 is rotatably connected to the fixing frame 41 and moves up and down therewith. The jaw assembly 43 is arranged on the rotary assembly 42 and is used for clamping and placing the short single-crystal rod 1 and rotates with the rotary assembly 42;

[0061] The fixing frame 41 includes a rod clamping assembly for restricting the rotary assembly 42 to be in a horizontal or vertical state.

[0062] In this embodiment, by providing the driving module 3 that cooperates with the rotary clamping module 4 to move it up and down, and the overall design concept of the fixing frame 41, the rotary assembly 42, and the jaw assembly 43 of the rotary clamping module 4 cooperating with each other, the jaw assembly 43 can be restricted by the fixing frame 41 to be in a horizontal or vertical state along with the rotary assembly 42. The jaw assembly 43 can clamp the short single-crystal rod 1 in the horizontal state and place the short single-crystal rod 1 in the vertical state. Furthermore, the short single-crystal rod 1 can be quickly taken out from the single-crystal furnace, directly transported to the storage point of the short single-crystal rod 1 by the cart main body 2, and then the short single-crystal rod 1 can be directly placed horizontally at the storage point by using the rotary clamping module 4, thus effectively solving the problem that the current finished product crystal picking cart is not applicable to the short single-crystal rod 1, and the operation efficiency of picking, placing, and horizontally placing the short single-crystal rod 1 is relatively low.

[0063] In some alternative embodiments, the driving module 3 includes a hydraulic cylinder 31, a support cross bar 32, a driving gear 33, a driving chain 34, a guiding support cylinder 35, a fixed support plate 36, and a guiding support plate 37, wherein:

[0064] The hydraulic cylinder 31 and the guiding support cylinder 35 are vertically arranged on the trolley main body 2. The fixed support plate 36 is fixed on the hydraulic cylinder 31 or / and the guiding support cylinder 35. The guiding support plate 37 is slidably connected to the guiding support cylinder 35 in the vertical direction, and the guiding support plate 37 is fixed on the fixing frame 41. The supporting cross bar 32 is arranged on the output end of the hydraulic cylinder 31. The driving gear 33 is sleeved on the supporting cross bar 32 and can rotate self - axially along it. The driving chain 34 is wound around the driving chain 34. One end of the driving chain 34 is fixed on the fixed support plate 36, and the other end is fixed on the guiding support plate 37.

[0065] In some alternative embodiments, the number of the guiding support cylinders 35 is two, and the two guiding support cylinders 35 are symmetrically arranged on both sides of the hydraulic cylinder 31;

[0066] Vertical sliding grooves are arranged on the opposite sides of the two guiding support cylinders 35, and the guiding support plate 37 is clamped in the sliding grooves and slidably connected thereto;

[0067] Both ends of the supporting cross bar 32 are respectively fixed on the two guiding support cylinders 35,

[0068] Both ends of the fixed support plate 36 are respectively fixed on the two guiding support cylinders 35.

[0069] As Figures 1 to 3 shown, in this embodiment, the number of the driving gears 33 is two, and the number of the driving chains 34 is two. The two driving chains 34 are respectively wound around the two driving gears 33. The two driving gears 33 are symmetrically arranged on the supporting cross bar 32. By setting the two symmetric driving gears 33 and driving chains 34, the force when the guiding support plate 37 is lifted and lowered can be balanced, and the maximum weight that can be carried can be increased.

[0070] In this embodiment, as Figure 1 and Figure 2 shown, the guiding support plate 37 is in a C - shape. The middle part of it is fixed on the fixing frame main body 411, and the other two sides are arranged between the two guiding support cylinders 35 and are respectively slidably connected thereto. In this embodiment, there are two guiding support plates 37 with the same structure up and down, so that the fixing frame main body 411 is more stable when moving up and down through the guiding support plates 37.

[0071] In some alternative embodiments, the jaw assembly 43 includes a first jaw arm 431, a second jaw arm 432, a first jaw head 439, a second jaw head 430, and a bidirectional screw 433. The first jaw head 439 is disposed within the first jaw arm 431 and is hinged thereto. The second jaw head 430 is disposed within the second jaw arm 432 and is hinged thereto. Opposite ends of the bidirectional screw 433 that rotate in opposite directions are respectively connected to the first jaw head 439 and the second jaw head 430 in a helical manner. The middle of the bidirectional screw 433 has a snap ring that is movably connected to the rotating assembly 42.

[0072] In this embodiment, the lengths of the two portions of the bidirectional screw 433 that rotate in opposite directions are the same. As Figure 10 shown, when the bidirectional screw 433 rotates, the first jaw head 439 and the second jaw head 430 that are helically connected to the bidirectional screw 433 will simultaneously approach or move away from each other. Consequently, the first jaw arm 431 and the second jaw arm 432 that are respectively hinged to the first jaw head 439 and the second jaw head 430 will simultaneously approach or move away from each other. As Figure 5 shown, both the first jaw arm 431 and the second jaw arm 432 are hinged to the rotating support frame 421. Therefore, when the first jaw arm 431 and the second jaw arm 432 approach each other, the ends of the first jaw arm 431 and the second jaw arm 432 that are away from the bidirectional screw 433 will move away from each other. Conversely, when the first jaw arm 431 and the second jaw arm 432 move away from each other, the ends of the first jaw arm 431 and the second jaw arm 432 that are away from the bidirectional screw 433 will approach each other. The first jaw head 439 and the second jaw head 430 in this embodiment have the same structure and are both block-shaped.

[0073] In some alternative embodiments, the jaw assembly 43 further includes a crank 434 fixedly connected to one end of the bidirectional screw 433. In this embodiment, as Figure 5 and Figure 10 shown, the crank 434 is L-shaped. The crank 434 is inserted into one end of the bidirectional screw 433 close to the rocker 423 and is detachably connected to the bidirectional screw 433. As Figure 6 shown, the crank 434 and the rocker 423 are disposed on the same side, which facilitates operation by the operator, enabling the operator to avoid moving left and right on the cart body 2, making the operation more convenient.

[0074] In some alternative embodiments, the fixed connection between the crank 434 and the bidirectional screw 433 is a detachable connection.

[0075] In some alternative embodiments, the fixed connection between the crank 434 and the bidirectional screw 433 is a welding connection. In certain embodiments, the fixed connection between the crank 434 and the bidirectional screw 433 can also be an integrally formed connection.

[0076] In some alternative embodiments, the jaw assembly 43 further includes a first clamping plate 437 and a first heat insulation plate 435 disposed on the first jaw arm 431, and a second clamping plate 438 and a second heat insulation plate 436 disposed on the second jaw arm 432. The first heat insulation plate 435 and the second heat insulation plate 436 are disposed between the first clamping plate 437 and the second clamping plate 438.

[0077] In this embodiment, by providing the first heat insulation plate 435 and the second heat insulation plate 436 between the first clamping plate 437 and the second clamping plate 438, when the short crystal bar 1 is taken out of the single crystal furnace, the heat of the short crystal bar 1 can be prevented from quickly transferring to the first clamping plate 437 and the second clamping plate 438, resulting in rapid heat dissipation of the short crystal bar 1 and causing stress concentration in the short crystal bar 1, which affects the product quality. The first heat insulation plate 435 and the second heat insulation plate 436 in this embodiment are common heat insulation materials and will not be elaborated here. Additionally, since the weight of the short crystal bar 1 is relatively large, the weight of the short crystal bar 1 can even reach 150 kg. Therefore, the first clamping plate 437 and the second clamping plate 438 in this embodiment are made of iron plates or steel plates to enhance the strength of the jaw assembly 43 and improve the durability of the product.

[0078] In some alternative embodiments, as Figure 8 and Figure 9 shown, the rotating assembly 42 includes a rotating support frame 421 with a C-shaped longitudinal section, a limiting column 426 disposed between the upper and lower ends of the rotating support frame 421, and two vertical limiting plates 425 disposed inside the rotating support frame 421, where:

[0079] On the opposite sides of the two vertical limiting plates 425, rolling grooves are respectively provided, and the clamping rings of the bidirectional screw 433 can roll back and forth in the rolling grooves;

[0080] Both the first jaw arm 431 and the second jaw arm 432 are hinged to the rotating support frame 421;

[0081] It further includes a rotating shaft 422 fixed to the rotating support frame 421 and rotatably connected to the fixed frame 41. The rotating shaft 422 is disposed on a side of the rotating support frame 421 away from the first jaw arm 431 and the second jaw arm 432.

[0082] As Figure 8 shown, rolling grooves are respectively provided on the opposite sides of the two vertical limiting plates 425. As Figure 10 shown, the clamping ring of the bidirectional screw 433 is located at the middle position thereof. After the jaw assembly 43 is installed on the rotating assembly 42, the clamping ring of the bidirectional screw 433 is located in the rolling grooves of the limiting plates 425.

[0083] In use, since both the first clamping arm 431 and the second clamping arm 432 are hinged to the rotating support frame 421, and the first clamping arm 431 is hinged to the first chuck 439, the second clamping arm 432 is hinged to the second chuck 430, and the first chuck 439 is screwed to one end of the bidirectional screw 433, and the second chuck 430 is hinged to the other end of the bidirectional screw 433. Therefore, when the bidirectional screw 433 rotates, the rotating bidirectional screw 433 will drive the first chuck 439 and the second chuck 430 to approach or move away from each other. At this time, the approaching or separating first chuck 439 and second chuck 430 will drive the first clamping arm 431 and the second clamping arm 432 to swing respectively along their hinge points with the rotating support frame 421. And since the first chuck 439 and the second chuck 430 are both screwed to the bidirectional screw 433, the first chuck 439 and the second chuck 430 can only move in the axial direction of the bidirectional screw 433. Therefore, when the first clamping arm 431 and the second clamping arm 432 swing respectively along their hinge points with the rotating support frame 421, the screw will roll forward or backward in a direction perpendicular to its axis. And the positioning ring of the bidirectional screw 433 is located in the rolling groove of the limiting plate 425, which can cause the two sides of the rolling groove to exert a limiting effect on the positioning ring, so that the positioning ring can only roll in the rolling groove, making the first chuck 439 and the second chuck 430 in a symmetrical state when moving on the bidirectional screw 433, and further making the first clamping arm 431 and the second clamping arm 432 swing symmetrically to clamp or place the short crystal bar 1.

[0084] In some alternative embodiments, the rotating assembly 42 further includes a first bearing 427 and a second bearing 428 disposed on the fixing frame 41, and the rotating shaft 422 is disposed within the first bearing 427 and the second bearing 428.

[0085] In this embodiment, as Figure 11 shown, a first bearing support 416 and a second bearing support 417 are further disposed on the fixing frame main body 411, and the first bearing support 416 and the second bearing support 417 are in the same horizontal state. The first bearing support 416 is rod-shaped and disposed at the middle position of the fixing frame main body 411, and the second bearing support 417 is located on one side of the fixing frame main body 411 away from the transverse clamping bar assembly and the vertical clamping bar assembly. As Figure 4 and Figure 7 shown, the first bearing 427 is mounted on the first bearing support 416, and the second bearing 428 is mounted on the second bearing support 417.

[0086] In some alternative embodiments, the rotating assembly 42 further includes a rocker 423 hinged to the rotating shaft 422, and a tension spring with one end fixed to the rotating shaft 422 and the other end fixed to the rocker 423, and the tension spring 424 is located on the side of the rocker 423 away from the rotating support frame 421;

[0087] One end of the rocker 423 away from the rotation axis 422 can be clamped in the clamping rod assembly through the tension spring 424, so that the rotating support frame 421 is in a horizontal or vertical state. By providing the rocker 423 hinged to the rotation axis 422 and the tension spring 424 fixedly connected to the rocker 423 and the rotation axis 422 respectively, the rocker 423 can be offset towards the fixed frame 41 under the pulling of the tension spring 424. After one end of the rocker 423 away from the rotation axis 422 is clamped in the clamping rod assembly, the tension spring 424 can maintain the rocker 423 in the clamping rod assembly, so that the rotating support frame 421 is stably in a horizontal or vertical state.

[0088] In some alternative embodiments, the fixed frame 41 includes a fixed frame body 411, and the clamping rod assembly includes a horizontal clamping rod assembly and a vertical clamping rod assembly both horizontally arranged on the fixed frame body 411;

[0089] When the rocker 423 is clamped in the horizontal clamping rod assembly, the jaw assembly 43 is in a horizontal state along with the rotating support frame 421;

[0090] When the rocker 423 is clamped in the vertical clamping rod assembly, the jaw assembly 43 is in a vertical state along with the rotating support frame 421.

[0091] In some alternative embodiments, the horizontal clamping rod assembly includes a horizontal long clamping rod 414 and a horizontal short clamping rod 415 horizontally fixed to the fixed frame 41;

[0092] The vertical clamping rod assembly includes a vertical long clamping rod 412 and a vertical short clamping rod 413 horizontally fixed to the fixed frame 41;

[0093] The horizontal short clamping rod 415 and the vertical short clamping rod 413 are arranged between the horizontal long clamping rod 414 and the vertical short clamping rod 413, which can facilitate the operator to clamp the rocker 423 in the horizontal clamping rod assembly or the vertical clamping rod assembly.

[0094] In this embodiment, as Figure 11 shown, the horizontal short clamping rod 415 is arranged close to the horizontal long clamping rod 414, and the vertical short clamping rod 413 is arranged close to the vertical long clamping rod 412. When the rocker 423 is clamped between the horizontal short clamping rod 415 and the horizontal long clamping rod 414, as Figure 4 shown, the rotating support frame 421 and the jaw assembly 43 are both in a horizontal state. At this time, the jaw assembly 43 can be used to clamp the short crystal bar 1 in a vertical state. When the rocker 423 is clamped between the vertical short clamping rod 413 and the vertical long clamping rod 412, the rotating support frame 421 and the jaw assembly 43 are both in a vertical state. At this time, the short crystal bar 1 clamped by the jaw assembly 43 is in a horizontal state.

[0095] When using this embodiment, move the trolley main body 2 to the corresponding position for removing the short single crystal bar 1, and then start the hydraulic cylinder 31, so that the support cross bar 32 at the output end of the hydraulic cylinder 31 moves upward. Since the drive gear 33 is sleeved on the support cross bar 32 and the drive chain 34 is wound around the drive gear 33, and the two ends of the drive chain 34 are respectively fixed on the fixed support plate 36 and the guide support plate 37, therefore, when the support cross bar 32 moves upward, it will drive the drive chain 34 to move upward, and then drive the guide support plate 37 to move upward, and then drive the fixed frame main body 411 to move upward, and then drive the rotary clamping module 4 to move upward to the short single crystal. Subsequently, make the first heat insulation plate 435 and the second heat insulation plate 436 be located on both sides of the short single crystal respectively, and then shake the crank 434, so that the bidirectional screw 433 rotates, and the first heat insulation plate 435, the first clamping plate 437 and the second heat insulation plate 436, the second clamping plate 438 approach each other, and then clamp the short single crystal bar 1. Subsequently, place the short single crystal bar 1 on the trolley main body 2. At this time, as Figure 1 shown, then, transport the short single crystal bar 1 to the storage point of the short single crystal bar 1. When storing, first clamp the short single crystal bar 1 by using the jaw assembly 43, and then shake the rocker 423, so that the rocker 423 is stuck between the vertical short clamping rod 413 and the vertical long clamping rod 412, so that the short single crystal bar 1 is in a horizontal state, and then use the drive module 3 to drive the short single crystal bar 1 to the corresponding position and then it can be placed.
